TUCSON -- The best TV weatherman surely is Chuck George at KOLD 13. He does a great job explaining complex climate science to general audiences.
Today Chuck did a great job explaining why Tucson smog was bad today and how it jumps in the summer with intense sun mixed with auto & industry pollution, causing harmful ground level ozone locked in by our surrounding mountains.
Today ozone was in the 'moderate' category, which means bad for you. I rode my bike, and coughed a few times.
